DANA L. CHESTER/MAN AND FRANK E. GHESTERMAN, OF PHILADELPHIA, PENNSYL- VANIA.

HERNIAL TRUSS.

Application filed November 18, 1921. Serial No. 516,043.

To all whom it may concern:

Be it known that we, DANA L. Cransrnn- MAN and FRANK E. CHns'rnRMAN, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Hernial Truss, of which the following is a specification.

Our invention consists of a hernial truss in which a plate is adapted to support the pad, and further adapted to be disconnect-- ed from the pad and body band without removing the connecting respective screws thereof.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claim.

Figures 1 and 2 represent front elevations of a portion of a hernial truss embodying our invention showing the pad thereof applied respectively in right and left positions.

Figure 3 represents a front elevation of the pad and plate showing the plate in position to be removed from the pad or vice versa.

Figure 4 represents a section of a portion on line 44 Figure 3.

Similar numerals of reference indicate corresponding parts in the figures. Referring to the drawings.

1 designates a pad of a hernial truss, and 2 designates the body band or belt thereof. 3 designates the plate adapted to connect said pad with said band and vice versa, said plate being of curved or segmental form and having therein a slot which extends curvilinearly in the direction of the length thereof.

4 desigi'lates screws whose shanks are r passed through the terminal portion 5 of the slot in the plate into the pad 1, and whose heads overlap the walls of said portions 5, so that when said screws 4 are tightened the pad is connected firmly with said plate and vice versa. 6 designates screws whose shanks are passed through the terminal portion 7 of the slot in the plate into the band to and whose heads overlap the walls of said portion 7 so that when said screws 6 are tightened the plate is connected firmly with said band and vice versa. The slots 5 and 7 are matched so that either end of the plate is adapted to be connected with the pad or body band and it is reversible as shown in Figures 1 and 2.

The central portion of the slot 5 is wider than the end portions 5 and 7 thereof and forms athroat which is a continuity of said end portions and of greater width than the diameters of the heads of the screws 4 and 6, so that said heads may pass through said throat while the end portions 5 and 7 of the slot are of less diameters than the heads of said screws whereby said heads cannot pass through said end portions 5 and 7 they overlapping the walls of the latter and being adapted to be tightened thereon as above stated.

When it is desired to disconnect the pad from the plate or vice versa the screws 4 are loosened whereby the pad may be moved on the plate or vice versa until said screws reach the wide portion of the slot or throat 8 and occupy the same, see Figure 4, when as the heads of said screws are of less diameter than the width of said throat 8 of the slot said heads may be passed out through said throat thus disconnecting the pad and plate, this being accomplished without removing the screws 4 from the pad.

hen it is desired to disconnect the plate from the band or vice versa, the screws 6 are loosened whereby the plate may be moved on the band or vice versa until the said screws reach the wide portion 8 of the slot, see Figure 3, when as the heads of said screws are of less diameter than the width of said wide portion 8 of the slot said heads may be passed out through said wide portions of the slot thus disconnecting the plate and band this being accomplished without removing the screws from the band.

it is evident that the plate may be reversed for the right or left position of the pad as the case may be, and the heads of the screws 4 passed through the wide portion 8 of the slot and the pad or plate moved until the shanks of said screws occupy the portions 5 of the slot and the pad is properly adjusted. Then the screws 4 are tightened and so the pad and plate are firmly connected.

Then the heads of the screws 6 may be passed through the wide portion 8 of the slot and the plate moved until the hanks of said screws occupy the portion 7 of the slot. The screws 6 are then tightened and so the plate and band are firmly connected.

In these manipulations of reassembling thetruss, the screws 4 and 6 have remained primarily on the pad and band and only re quire tightening to effect the retention of parts in their reversed adjusted position.

Having thus described our invention What we claim as new and desire to secure by Le ters Patent is In a truss, a pad, a body band, a reversible plate and securing and adjusting screws, said plate ha ving;- therein a slot continuous from end toend of the plate the portion of said slot intermediate of the end ortions thereof being of greater Width t an the Widths of said end portions and being a communicatingcontinuity of the latter.
